Dab tsi yog cov yam ntxwv ntawm daim ntawv thov ntawm insulating board?

Rwb thaiv tsev board tseem hu ua epoxy resin board, epoxy fiberglass board, 3240 epoxy fiberglass board, uas yog yus muaj los ntawm muaj zog adhesion thiab muaj zog shrinkage. Nws yog qhov tsim nyog rau cov khoom siv hluav taws xob, hluav taws xob thiab hluav taws xob nrog cov rwb thaiv tsev siab, nrog cov khoom siv hluav taws xob siab thiab dielectric, nrog rau cov cua sov zoo thiab cov dej tsis zoo.

Puas yog qee tus ntawm peb cov neeg siv khoom nug txog qib ntawm epoxy resin rwb thaiv tsev boards? Qhia lawv kom ntxaws. Raws li ib txwm muaj, cov neeg siv khoom feem ntau hais txog B, F, H … cov qib no yog cov qib kub-resistant kub ntawm cov ntaub ntawv insulating.

Insulating board yog ib yam khoom siv insulating, thiab nws cov insulating kev ua tau zoo heev cuam tshuam rau qhov kub thiab txias. Qhov siab dua qhov kub, qhov ua tau zoo ntawm kev ua haujlwm insulating. Txhawm rau kom cov rwb thaiv tsev muaj zog, txhua cov khoom siv insulating muaj qhov tsim nyog ua haujlwm kub, uas yuav tsum tau peb thaum siv cov ntawv insulating, koj yuav tsum tswj qhov kub kom haum. Qhov no kuj yog ib txoj hauv kev zoo los tswj cov ntawv roj hmab, vim tias nyob rau hauv qhov kub thiab txias, tsis tsuas yog kev rwb thaiv tsev ntawm cov ntawv roj hmab tsis zoo, tab sis cov ntawv roj hmab kuj tseem yuav muaj hnub nyoog sai.

Kev sib raug zoo ntawm qhov kub thiab txias ntawm epoxy resin rwb thaiv tsev board thiab cov chav kawm ntawm rwb thaiv tsev kub: Raws li cov qib ntawm cov cua sov, cov ntaub ntawv rwb thaiv tsev muab faib ua Y, A, E, B, F, H, C thiab lwm qib. Piv txwv li, qhov tso cai ua hauj lwm kub ntawm Class A insulating cov ntaub ntawv yog 105 ° C, thiab feem ntau ntawm cov ntaub ntawv insulating siv nyob rau hauv tis transformers thiab motors feem ntau yog rau Class A, xws li epoxy resin rwb thaiv tsev boards thiab hais txog.
